Application filed August 14,1918. Serial No. 249,839.

To all whom it may concern:

Be it known that I, ALEX S. CRAWFORD, a citizen of the United States, residing at Cannonsville, in the county of Delaware and State of New York, have invented new and useful Improvements in Horseshoes, of which the following is a specification.

This invention relates to horse shoes, and the object is to provide detachable heel calks and a detachable toe call; secured in position by means of a threaded fastening device, making it unnecessary to force the calks into position by driving the latter or turning them. as when the calks themselves are provided with threads.

A further object is to provide a shoe having a transverse undercut channel at the toe with certain novel reinforcing means adjacent to the channel, and a channel of a similar character at the heel portions for the purpose of receiving calks formed with tapered sides engaging the undercut walls of the channels.

A still further object is to provide a shoe of the type indicated reinforced adjacent the walls of the channels by means of projecting rounded portions of metal assuming the form of enlargements which may for convenience be termed patches.

\Vith the foregoing and other objects in view, the invention consists in the novel construction, combination, and arrangement of elements hereinafter described and claimed.

In the drawings, Figure l is a plan view of the device, Fig. 2 is a section on line 22 of Fig. 1, and

Fig. 3 is a detail view of one form of the calk.

The shoe proper is designated 10 and includes a toe portion 12 and heel portions 13 and 14. The toe portion is provided with a transverse channel 15 having undercut walls 16 engaging the inclined walls 17 of the toe calk 18. The end portions of the toe calk are also inclined as shown at 19. The toe calk is secured by means of a screw 20, entering the arch portion of the shoe and en gaging the calk for the purpose indicated.

The heel portions 13 and 14 are also pro vidcd with channels extending transversely and designated 23 and 2%, and these chan nels have undercut walls retaining in posi- "ion the calks 25 and 26 formed in the manner above described.

The heel portions and also the toe portions are reinforced at points adjacent to the side walls of the channel by means of thickened portions of metal, or enlargements, designated 30. Certain of these enlargements may be provided with straight edge portions as shown at 31, others being circular in outline and if desired having a convex surface. The object is to protect the walls of the slots where they would otherwise be weakened, and the object is further to provide more surface for contacting with the calks, retaining them more securely in position.

In the form shown in Fig. 3 I provide a call; having cutaway portions in the sides thereof, a cutaway portion in the base, these portions constituting longitudinal channels having curved walls. In this form reinforcing members may project into the channels referred to. The channels are designated 33 and a toe calk as a whole is shown at It will be observed that I have provided a calk having walls which may be grooved, and which are outwardly inclined and tapered toward each other forming a sharp edge; and also reinforcements overlapping the edges of the undercut walls of the channels in the shoe, overlapping the walls of the calk and entering the grooves in the calk so provided, these reinforcing elements being in the form of patches or thickened portions.

hat is claimed is:

A horse shoe, having a transverse channel in the toe portion and in each heel portion thereof, said channels having undercut walls, calks having grooved and inclined side portions located in said channels, the inclined portions tapering outwardly toward each other, means for securing the calks in position, and reinforcing means on the surface of the shoe adjacent the calks, overlapping the walls of the channels bearing against the inclined faces of the calks and entering the grooves thereof, said reinforcing means comprising thickened portions of metal having rounded surfaces, certain of said thickened portions having undercut inclined edge portions engaging the adjacent calk.

In testimony whereof I aifix my signature.
